That was just basic materials at Menards, no labor and very little options, but, basic structure.
Yes, re-evaluate the design and materials. There is no way you will ever, ever, ever come close to a break-even on that price for a garage. Even 25k is going to be a stretch to break even.
My father built a simple pole barn that is pretty large for $10k, he did some labor himself, but not the heavy or high up stuff. Not fully done, and no concrete floor, but using for basic storage. He uses it to store his camper in the winter time.
